Sorry I wasn't able to respond earlier, love the interest in the graphics. I actually use Clean N' Natural: https://www.gta5-mods.com/misc/clean-n-natural-enb-preset
I'm very pleased with it, works very smoothly so it's definitely worth checking out.

The linked screenshot mentioned by @Kilyin is from quite a while ago, I didn't use Clean N' Natural back then. Note that I also do not edit my screenshots in any way anymore.
